Fun With Expanding One's Primary ...

[JRutledge]

This should be basically easy for the lead. The player came from his area, watch them and see what they do. He has no other competitive matchup during this play. Looks like he is ball-watching.

Peace

Agree.

He should have known that she was "up to something" and should have "monitored" her until other players more likely to "do something" appeared in his primary.

This is a Connecticut prep school (home in dark jersey is an odd Connecticut prep school rule).

How many other schools have a Wyvern for a mascot?

Hope the Wyverns don't find out that somebody has culturally appropriated and hijacking their image as a mascot.

Not only should lead have taken this, he should have "pinched the paint" to have a better look at it.

And, heck, T's matchup isn't so close that she couldn't have seen the coming screen to rule on it. That would be a good crew-saving call.

Agree. The ball handler/defender matchup wasn't really that competitive, and the illegal screen was visible within her field of vision at her distance from the players.

And it wasn't exactly a subtle illegal screen.

I can't disagree with the above comments...yes, illegal screen. Yes, this is the L's to get.

This play is a perfect illustration of the point I often try to make that PCA's are about on-ball coverage. The T is on-ball on the perimeter. The L must cover anything like this anywhere on the court and away form the ball. Even if this occurred halfway between the top of the key and the center circle, the L is the one that has to cover it.

The perils of a two person game.

Welcome to my world.

That's true even in three-person. The on-ball official watches the player with the ball and the defender. The other two officials each watch the two matchups nearest them.

(and, yes, I recognize the math associated with "nearest" doesn't always work that way)

Indeed. It does work in 3-person just the same, and, if the 3 are doing things right, a lot more of this kind of stuff doesn't get missed.

Agree with Bob, this should be easy call for L. Disagree with Bob, this is not a crew-saving call. There was no advantage gained by the offensive team, the screen did not work as planned and lead to an immediate scoring opportunity. Ultimately the girl they were screening for got the ball, much further from the basket than the offense was hoping for, while being guarded. This is a long way from a crew-saving call.

IAABO Play Commentary: Correct Answer: The Lead should expand his coverage area and rule and illegal screen..

This is an illegal screen. The screener has a stance wider than shoulder-width, was still moving, and did not give the opponent the time and distance needed when screening a player outside their visual field. (4-40-2c, 2d, 4-40-5)

These types of high post screens can pose a challenge to a 2-person crew. When the ball was passed to the sideline, the Trail official properly maintained focus on the ball handler/defender match-up near the sideline. In this situation, the Lead official needs to quickly assess where the competitive match-ups are on the court and determine where the greatest need is during the possession. In this case, the only other engaged competitive match-up at this moment (other than the ball handler/defender) was this screening situation.

Even though the screen technically occurs in the Trail's primary coverage area (PCA), officials must be willing to assist the partner in ruling on “off-ball” contact in the secondary/expanded coverage area (SCA) when the ball is in the partner’s PCA. (IAABO manual p. 20 Section 6.d) On this play, we encourage the Lead to expand their coverage and look "outside their area" to rule this illegal off-ball contact.

Here is the breakdown of the IAABO members that commented on the video: The Lead should expand his coverage area and rule and illegal screen 89% (including me). The Lead should not expand his coverage area and make a ruling on this play 11%.
